Following on from this thread : http://www.cpcwiki.eu/forum/nc100-nc200-pcw-pda600/got-amstrad-pcw-8256-but-the-fun-don't-lasted-very-long-o/


I have a PCW9512 that stopped working for no reason. It is completely dead, and I would like to start using it. I read the thread and tried to swap out the STK7309 for a known good STK7308 (from a PCW8256). They seem to have equivalent outputs and ratings. Anyway, I was disappointed to find that the machine is still dead.


Can anyone advise me on what to check next?


Many thanks
